Amazon has the 650s on sale right now 315USD should i just pick those up or do you guys think these massdrop 6xx are unique enough to order? I will have to buy an amp for listening from my computer most likely.

It really comes down to whether you think the extra $115 of the 650 over the 6XX is worth the immediate shipping vs receiving a pair in march. The only real difference between the two is cosmetic, the sound signatures are identical. I think the 6XX look better personally and I didn't really mind waiting a few months. You could also check out the 600s on ebay or amazon for under 300 with relatively fast shipping as well.
